I bought one at $469 with a $20 rebate just three days ago!  I am kind of pissed.  I may just send it back.  Let us know if they give you a refund for the difference.  I suspect they won't.

Newegg claims they'll price-match their own changed prices within 7 days. It's a shitty policy (I've never seen anything less than 14, and most are 30), but if you say it's only been 4 or 5 days at this point, hit up their Chat.

Thanks I will do that.  Will let everyone know what happens.  Hopefully the fact that am I about to drop another $1000 with them will help Smiley

I love Newegg!  Most free shipping has only been taking two or three days.  That's pretty awesome.  I ordered my Vega Monday night and had it Wednesday!

423  Alternate cryptocurrencies / Mining (Altcoins) / Wattman sucks! Can OverdriveNTool completely replace the need for Wattman? on: November 04, 2017, 02:35:12 AM
I so sick of Wattman.  Lack of profile support and constant crashing/resetting of parameters.  Come on AMD, this is pathetic.

I just discovered OverdriveNTool.  I like what I see so far but I need to know if it is safe to uninstall Wattman and rely completely on Overdrive?

It's my first post on this form and I take the opportunity to thank you all (Mythic in special) for you knowledge sharing.
Below you can find my experience with both RX Vega 56 and 64 version mining Monero @ 1800-2000 h/s:

Both my rigs have the same configuration except GPU type:
-  8 x GPU (8 x RX Vega 56 on first rig and another 8x RX Vega 64 on 2'nd) , Biostar B250 BTC-PRO, 8GB-RAM DDR4, SSD 120GB (65GB Virtual memory in Win10).
-  Software config: Blockchain driver, Soft PPT in registry, disable-enable display adapter after restart,  cast miner 6.0
-  Result:~1800 H/s on all 8 pcs Vega56 and ~2000 H/s on all 8 pcs Vega64
-  Print screen with the results:

https://drive.google.com/file/d/1LlhIxuc4MFVbUog50BKigv-aqV-RXuCp6g/view?usp=sharing

Coming soon: please be prepared for one of the most interesting rig (8 GPU in a semi open case with  a horn on top for hot air exhaust)


I hadn't originally planned on putting this out there, but some other asshole decided to charge a fee for this info. Fuck that guy. Here's a fix for reduced hashrate and a method for running 4+ Vega at full speed while mining XMR.

Basic Users:

1. Use the Blockchain drivers.
2. Open up your device manager.
3. Open up the "Display Adapters" dropdown.
4. Right click on one of your Vega's.
5. Disable it.
6. Wait a few seconds.
7. Right click on the Vega you just disabled.
8. Re-enable it.
9. Repeat steps 4-8 for the rest of your cards.
10. Enjoy mining at full speed with as many Vega as you damn well please. Probably.

Advanced Users:

The previously described process is a bit of a pain in the ass. Let's automate it.

New Procedure

1. Get your hands on the Windows Device Console (Devcon.exe). This will let you disable/enable devices from console.
2. Create a batch file in the same folder as devcon.exe with the following lines in it:
Code:
cd %~dp0
timeout /t 5
devcon.exe disable "PCI\VEN_1002&DEV_687F"
timeout /t 5
devcon.exe enable "PCI\VEN_1002&DEV_687F"
3. This will selectively disable/enable all the Vega cards you currently have in your system. Thanks to bytiges for noting that killing all the display adapters might not be a good idea for those using iGPU.
4. Run the batch file as an administrator at login, or whenever you lose hashrate on your cards. Enjoy never having to toggle the HBCC switch again.

Outdated Procedure

1. Get your hands on the Windows Device Console (Devcon.exe). This will let you disable/enable devices from console.
2. Run the command devcon.exe FindAll * to generate a list of all the currently attached devices and their hardware IDs.
3. Search your newly generated list for "Radeon RX Vega." You should find something like this:
Code:
PCI\VEN_1002&DEV_687F&SUBSYS_0B361002&REV_C3\6&3AAC35E3&0&000000E7 : Radeon RX Vega
4. The part to the left of the colon is what you need. Shocking, I know. Put that thing into a batch file that looks something like this:
Code:
@echo on
cd C:\Users\Mythic\Desktop\Startup
timeout /t 5
devcon.exe disable PCI\VEN_1002&DEV_687F&SUBSYS_0B361002&REV_C3\6&3AAC35E3&0&000000E7
timeout /t 15
devcon.exe enable PCI\VEN_1002&DEV_687F&SUBSYS_0B361002&REV_C3\6&3AAC35E3&0&000000E7
timeout /t 15
OverdriveNTool.exe -p0Vega0 -p1Vega1 -p2Vega2 -p3Vega3 -p4Vega4 -p5Vega5 -p6Vega6
timeout /t 10
cd C:\Users\Mythic\Desktop\xmr-stak-amd
xmr-stak-amd.exe
5. Run your batch file at startup as an administrator. Enjoy never having to toggle the HBCC switch again.

FAQ:

Q: So, Mythic, how exactly does this enable HBCC on cards 5-7?

A: It doesn't! HBCC Does nothing to improve your hashrate! Turns out the drivers are just shit and are bugged when Windows first boots up. Who would have guessed?

Q: But Mythic, does that mean I don't need 16 GB of ram to run my cards at full speed?

A: Correct! 4 GB of ram is completely sufficient!

Q: If I wanted to donate some pizza money to the broke ass college student that typed this up, how would I do so?

A: You ask the best questions! I doubt I'll get anything before more well known people/websites copy everything I just said (with no credit, obviously), but here are some addresses just in case.

Has anyone switched off Monero and onto something else?

Monero has been great for me the last few months. Just curious if anyone has played with any coins besides xmr or eth

Edit - just looked at whattomine 1080ti. My revenue off monero is still beating this card. So I think I just answered my own question

Yea well, monero with any other gpu or cpu is just stupid Cheesy But it seems ETH dual mining with polaris or gtx 1070 is closing on to vega monero. Then there is zencash which is better than zcash and has potential.

Zencash seems to be the hot Nvidia coin lately.  1070s should be dropping in price a lot between the Vegas dropping and the new 1070ti coming out.  I am going with Vega cards for the time being as they are more flexible in what can be mined and the Monero profitability is awesome right now.  Though I kind of waiting to see what happens with Bitcoin Gold.
428  Alternate cryptocurrencies / Marketplace (Altcoins) / Re: NEO coming to Ledger Nano S on: November 02, 2017, 04:45:54 PM
I have only used BTC and ETH on my Nano S.  How many apps can you install on it before you run out of memory?

I will probably pick up some NEO finally once the Nano can be used to secure it.
429  Alternate cryptocurrencies / Mining (Altcoins) / Re: [Cast XMR] high speed XMR/CryptoNight miner for RX Vega GPUs (2 KHash/s) on: November 02, 2017, 04:42:34 PM
you should get 2kh/s with vega56 and 2.07kh/s with vega56 with right tuning. 150-160watt.

So what could be the problem that I'm only getting 1300-1400?  I've already tweaked Wattman and the card is running pretty cool.

xmr-stak uses two threads per card, is Cast doing something like that internally and transparent to the user?

Sounds like HBCC isn't enabled, which seems to happen after a system restart. Have you tried resetting your cards within Windows? This always fixes my issues. There's a reference to a Microsoft file called devcon.exe - You have to jump through a couple of hoops to get it, but just follow this (and 'amd64' just means x64).

It's working great now, 1870 H/s on my Vega 56.  HBCC isn't required, nor is 8GB of RAM.  Just disable and enable the GPU using Device Manager after booting.

SAPPHIRE Radeon RX Vega 56 DirectX 12 100420L 8GB 2048-Bit HBM2 CrossFireX
$399

SAPPHIRE Radeon RX VEGA 64 DirectX 12 100410L 8GB 2048-Bit HBM2 HDMI / TRIPLE DP (UEFI) PCI Express 3.0 CrossFireX Support ATX Video Card
$499.99

Newegg right now.

(those are the MSRP price), sad for those who pay $600+ per card few weeks ago.

Notice that only SAPPHIRE are selling the cards at thos price, other brands still have high prices...

I just paid $469 for the Gigabyte Vega 56 with $20 rebate.  It is now $419 and still has the $20 rebate.  Limit 1 per rebate of course.

I wonder if these prices are the new normal or just a temporary dip?  I plan on picking up 3 more cards in the next week.

I didn't like the blocky form factor of the Vegas at first but I do now.  They look a lot better in the rigs than the hodgepodge of fans and heatsinks of the RX and Nvidia cards.  The Vegas actually look slim compared to RX580s.  The blower fans are way too loud though.
431  Alternate cryptocurrencies / Mining (Altcoins) / Re: Any word on amd vega hash rates? on: November 02, 2017, 02:10:30 PM
I finally got xmr-stak working.  Getting 1717 H/s with xmr-stak-amd on my Vega 56 after doing the "disable GPU then enable GPU" trick in Device Manager.  Before the trick I was only getting 1170 H/s.  This is with 4GB RAM.  Hope AMD can fix this issue with a new driver soon.  Cast_xmr is getting 1713-1734 H/s, basically the same.  Note that this is with stock Wattman settings.  By setting memory to 950, frequency to -30%, and power to -20% I have hit 1870 H/s!  Excellent.

Now I just have to script the GPU disable/enable after boot.  It's great that I can still use only 4GB of RAM.  The only unknown at this point is if Wattman is going to keep resetting back to defaults.  Wattman sucks.  It desperately needs profiles.

433  Alternate cryptocurrencies / Mining (Altcoins) / Re: Trying a Vega 56 - questions, issues on: November 02, 2017, 04:25:18 AM
Mining Moneros with the Vega56 is awesome and using cast-xmr mining does help even more.
Great combo.
1550 hash with the two and this is no tweaking of the AMD memory.


1550 with one Vega 56?  I thought you can achieve 1800+ with xmr-stak with some minor Wattman tweaks?
434  Alternate cryptocurrencies / Mining (Altcoins) / Re: Any word on amd vega hash rates? on: November 02, 2017, 03:54:43 AM

Holy hell, bought 4 of the Gigabyte branded ones 10 days ago. Sent an email to Newegg CS, I sure hope they honor their own price...

I bought one at $469 with a $20 rebate just three days ago!  I am kind of pissed.  I may just send it back.  Let us know if they give you a refund for the difference.  I suspect they won't.
435  Alternate cryptocurrencies / Mining (Altcoins) / Re: Trying a Vega 56 - questions, issues on: November 02, 2017, 03:50:03 AM
So I just got a Gigabyte Vega 56 to try out.   There doesn't seem to be a lot of threads out there yet about Vega mining so hopefully this thread can contribute some useful information.

Here's some data:

Stock settings out of the box I get 32.7 Mh/s on ETH.   The hash rate drops after four minutes fairly quickly to 30 Mh/s due to temperature increase to 75C.

Increasing the memory clock to 950 from the stock 800 gets the hash rate to 38.9.

If you're running Vegas how many are you running per rig?  Are you running with mixed RXs and/or Nvidias?

*more content to follow*



You need some tweak (like the ones on the RX 4x0/5x0 cards).

Monero right now is awesome on those cards.

Monero is what I am aiming for but I need to increase RAM to 8GB first.  It will be awesome if I can truly squeeze almost $3/day out of the Vega 56 (before electric).

In the last few pages from the above link you will find out you need only 4GB for 8x vega at least. Just disable and enable ur cards in device manager.

I just saw that post, that is great news.  Unfortunately I am having a hell of a time getting xmr-stak to work.  I don't know why this is so difficult.
436  Alternate cryptocurrencies / Mining (Altcoins) / Re: Any word on amd vega hash rates? on: November 02, 2017, 03:47:02 AM
But these Vega cards are sooooo expensive!  I will be sticking with the 1080ti's for the foreseeable future.  How long will it take to see ROI with the Vega's?

I just picked up a Vega 56 for $449 after rebate.  That makes it very competitive, especially if you can get the 1850 H/s with Monero.

They are 399

Man the price dropped $50 since Sunday!  My timing always sucks at EVERYTHING.

How do I set config.txt if I have 4 RX cards and just one Vega and just want to use the Vega?  I assume gpu_thread_num should be set to 1 and index should be set to what I think the index should be (in my case 4)?

I can't get it working with any index value though.
438  Alternate cryptocurrencies / Mining (Altcoins) / Re: [Cast XMR] high speed XMR/CryptoNight miner for RX Vega GPUs (2 KHash/s) on: November 02, 2017, 03:19:03 AM
I finally got Cast to work using -G 4 -opencl 2.  

Is there some way to determine what GPU index numbers are?

I'm only getting 1410 max hash/sec so far.  Freq -30%, memory 950MHz, power -20%.  What can I do to improve that?  I am expecting 1800+, that's what I've read I should get with xmr-stak and HBCC.  The Vega seems to crap out if memory is set to much above 975.

I'd really like to hear about the hashrates you can do on Zcash with this baby.  I'm still looking at 1080ti's for good ROI, but I'd like to hear numbers for the Vega

I normal do Zencash on the Nvidias and I wouldn't expect a very good hash rate on the Vega but I'll try it at some point.
